[Numpy-discussion] Build external C functions that take numpy arrays as parameters and return numpy arrays

[computer_guy]

Hi Everyone,

I am going to write some external C functions that takes in numpy
arrays as parameters and return numpy arrays. I have the following
questions:

1. What should I do in my C code?
2. Can I use any C compiler to build my library that takes numpy
arrays? I am using Windows XP and Visual Studio 2005.
3. How can I generate the python binding?

Thanks,
cg
